IF YOU WANT TO LEARN MORE ABOUT SOMETHING YOU WILL OBVIOUSLY HAVE QUESTIONS TO ASK YOURSELF THAT YOU WANT TO KNOW ABOUT IT. SAY YOU WANT TO LEARN MORE ABOUT SILTSTONE, A SEDIMENTARY ROCK, FOR SAY, A SCIENCE PROJECT. YOU WOULD PROBABLY ASK YOURSELF THESE QUESTIONS. 1. IS IT CLASTIC, ORGANIC, OR CHEMICAL? 2. WHERE DOES IT FORM? 3. HOW DOES IT FORM? 4. WHAT MINERALS ARE FOUND IN IT? 5. WHAT IS ITS GRAIN SIZE AND SHAPE? 6. IS IT UNIFORM OR NON-UNIFORM? 7. DO FOSSILS FORM IN IT AND IF SO WHAT KIND? 8. WHAT ARE SOME USES FOR IT?
Well first of all an Igneous rock is made from magma or lava. In other words, Igneous rocks are made purely by heat. Metamorphic rocks are made by heat and pressure. So that means Sedimentary rocks are made purely by pressure. ~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*
--Siltstone is often confused for shale. It is a clastic sedimentary rock. ----It has a fine grain size normally, but the grain is still coarse enough to be able to feel it. ------It’s grain shape is angular
Siltstone is almost always uniform. The only time it’s not is when it’s not pure siltstone. ~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*
Siltstone is made from grains of quartz usually held together by calcium carbonate, mica, clay, silica, and other minerals. -Red coloration indicates the presence of iron oxides --Greenish or gray coloration may indicate the presence of other compounds of iron. ~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*
Siltstone forms underwater in calm waters that bring the finest eroded material and settles them to the bottom. Those particles are pressed together to form a siltstone, which is between shale and sandstone. Siltstone forms by fine quartz particles and calcium carbonate or mica, clay, silica, and other minerals pressing together over a long period of time to form a fine-grained sedimentary rock. ~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*
Siltstone can be crushed and used as road metal. Siltstone is of very little use other than a contributor to soil.
--*Fossilized corals, bryozoa, jellyfish-like animals, and gastropods, a class of animals including snails and slugs, have been found in the siltstone deposits. ~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*
